What are the characteristics of the homologous series?
Characteristics are :
- The members of the homologous series have same functional group.
- Members have the same general formula.
- Members have the almost same chemical properties due to same functional group.
- Members have common general method of preparation.
What is the homologue of ch3 ch2 Oh?
Homologues of CH3CH2OH: CH3CH2CH2OH (propanol), CH3CH2CH2CH2OH (butanol),… Homologues of HCOOH: CH3COOH (ethanoic acid), CH3CH2COOH (propanoic acid),…
What is the homologous series of aldehyde?
A homologous series for aldehydes is methanal, ethanal, propanal, and butanal with chemical formulas of HCHO, CH3CHO, CH3CH2CHO, and CH3CH2CH2CHO, respectively where each successive compound differs from the previous one by a –CH2group.
What is a homologous series write any two characteristics of a homologous series?
Characteristics of a homologous series are: (i) Each member of the series can be represented by a general formula. (ii) All the members of the series can be prepared by the same general methods. (iii) Physical properties change throughout the series in a regular way.
What is homologous series give an example list its three characteristics?
A homologous series is a series of carbon compounds that have different numbers of carbon atoms but contain the same functional group. For example, methane, ethane, propane, butane, etc. are all part of the alkane homologous series. The general formula of this series is CnH2n+2.
What is the succeeding homologue of ch3 ch2 ch2 Oh?
So, the homologue of propanal is butanal.
What homologous series is c3h8?
C3H8 belongs to the homologous series of alkanes.
What is homologous series Class 10?
> A homologous series is a series of hydrocarbons which have similar chemical properties and they share the same general formula. They are organic compounds having similar structure and functional groups. – They contain the same functional group throughout the series.
What homologous series is butanol?
Alcohol Homologous Series
| Name | Number of Carbon atoms | Molecular Formula CnH2n+1OH |
|---|---|---|
| Methanol | 1 | C1H2(1)+1OH = CH2+1OH = CH3OH |
| Ethanol | 2 | C2H2(2)+1OH = C2H4+1OH = C2H5OH |
| Propanol | 3 | C3H2(3)+1OH = C3H6+1OH = C3H7OH |
| Butanol | 4 | C4H2(4)+1OH = C4H8+1OH = C4H9OH |
What is a homologous series explain taking alcohol series as an example?
A series of compounds in which the same functional group substitutes for hydrogen in the carbon chain is called homologous series . Consider the homologous series of alcohols- methanol, ethanol, etc. Note that methanol (CH3OH) is obtained by replacing one of the H atoms with -OH group in the methane structure.
